Mapping of Contralateral Space in Retinotopic Coordinates by a Parietal Cortical Area in Humans

Sereno, M. I., Pitzalis, S., Martinez, A.·2001·Science

Abstract

The internal organization of a higher level visual area in the human parietal cortex was mapped. Functional magnetic resonance images were acquired while the polar angle of a peripheral target for a delayed saccade was gradually changed. A region in the superior parietal cortex showed robust retinotopic mapping of the remembered target angle. The map reversed when the direction of rotation of the remembered targets was reversed and persisted unchanged when study participants detected rare target reappearances while maintaining fixation, or when the eccentricity of successive remembered targets was unpredictable. This region may correspond to the lateral intraparietal area in macaque monkeys.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A human homologue of monkey LIP has been identified by retinotopic mapping and implicated in gaze-centered updating of visual space, as well as in response to looming visuo-tactile stimuli.

    “A human homologous of monkey’s LIP has been identified by using retinotopic mapping and has been implicated in gaze-centered updating of visual space (Sereno et al. 2001; Medendorp et al. 2003), as well as in response to looming visuo-tactile stimuli (Huang et al. 2018).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
